A pressure vessel with volume one m contains steam at 2000 kPa and 400°C. If the steam is allowed to cool just dry saturated.  final pressure and mass of steam 


Calculate the heat removed during the process change in entropy (1300 kPa; 6,5 kg; -2357,5 kJ; -4.202 kJ/K) Steam at 800 kPa and 0,95 dryness fraction is heated at constant pressure until the temperature is 250°C. 


Calculate the following: final volume (use steam tables) heat supplied per kg of steam and change in entropy.
